解決方式：使用了c:set  c:foreach

<div class="preview-block">
            <h2 class="pre-h2">${data.materials.title} </h2>
            <ul class="exp-content-list">
                ${data.materials.list[0]}
                ${data.materials.list.size()}
                <c:set var="index" value="0" /> 
                <c:forEach begin="0" end="${data.materials.list.size()}" step="1" >
                    <li class="list-item-1">
                    <div class="pre-text"><P>${data.materials.list[index]}</P></div>
                    </li>
                    <c:set var="index" value="${index+1}" />
                </c:forEach>
            </ul>
        </div>
